If two angles are both supplementary to the same angle, then the two angles are of equal measure. When two parallel lines are crossed by a third line, the same side interior angles will be supplementary. Any two consecutive angles in a parallelogram will also be supplementary.
A child of the Enlightenment movement, John Locke, wrote the Social Contract that first allowed the justification for America to break away from England. Enlightenment also câ¦ontributed to the ideas of equality, religious tolerance, and freedom of speech that was adapted by the US government.
